Method Detail

correctAnnotationPositions

public static void correctAnnotationPositions(Document document)

The positions in NIF are measured in codepoints, while Java counts in terms of characters. So we have to correct the positions of the annotations.

Parameters:

document - the Document for which the positions should be checked and corrected if necessary

checkPositionsForConspicuity

public static void checkPositionsForConspicuity(List<Span> spans,
                                                String text)

This method checks the given Span instances for simple errors, e.g., markings that start or end with a whitespace instead of an alphanumeric character. If errors are found, a waring is printed.

Parameters:

spans - the list of Span instances that should be checked

text - the text on which the Span instances rely on

printWarning

private static void printWarning(String text,
                                 int start,
                                 int end,
                                 String warningMsg)
